RG150 Loud rattle after new piston

[FruitLooPs]

Hey mate, did it sound like this at all?

http://www.youtube.com/watch?v=UCobQW2OiIU knocking noise makes me think bottom end even if it is doubtful since you reckon it wasn't bottom end.

And yeah, my RG has worn pvalve ports (not that vid, ain't my bike) and rattles like a mofo at idle sounds like a ball bearing rattling about. Doesn't thump/or thud though. Down south Oyster noticed that my bore was 0.5 oversize which isn't overly common apparently. Although the bike has high KMs so it figures.

You also probably want to take it easy for a bit before thrashing about on a new piston I would think.

Hmm sound similar but maybe not as bad...

ill compare tonight.

if you dont mind whats the piston rings and gaskets worth for a rg?

Around $90-100 for the kit which includes piston, rings, pin and circlips then add another $50-60 for the headgasket.

[Jase W]

more like $180-200 for the kit, $40 for the base gasket and $90 for the head gasket (just re-use the old one).

Hrm, was going off the price for a kr150 back when I had one :P

[ajturbo]

ummm KR150... is NOT a RG150....

the KR's are a lot cheeper....

but i would really be check your power valves NOW....

DO NOT START the bike or even kick it over untill you KNOW they are ok....

bring it around here and we can have a look for you..

[Jase W]

powervalves are sweet. well they were when i put them in anyways. i'll have to wait till i get my car sorted & a towbar fitted before i can take the rg anywhere, im not too keen to start it.

[ajturbo]

did you put them in the right way????..

[Jase W]

they only go in one way...

[ajturbo]

thats what you HOPE....

but i managed to put them in the wrong way... lucky i noticed...

[Jase W]

hmm.... im pretty sure i got them in the right way eh. i'd imagine it would be a big crunch and not much else otherwise - the bike still goes fine (not that i should be riding like that with a new piston - but im a silly bugger), powervalves seem to be doing their job fine eh. i think after xmas/ny is gonna be when ill have time to sort it out, for now it can sit. ive got till may to get it into fighting form.

It better be going by Saturday.

I wanna have a go.

[Jase W]

Haha nah mate itll have to wait - if we're lucky ill have it ready before the bdo so ill chuck it on a trailer and bring it up (bugger riding it up, been there done that).

[Jase W]

Update: Ive pulled the pv's out again - they are sweet (exactly as they were when they went in). I decided to temp fate and start it again so that I could make a video of it - http://www.youtube.com/watch?v=ZLZg5...page=1&t=t&f=b

One guy commented and said it sounded like big end. Hope not.

Does that help anyone?
